STMicroelectronics STEVAL-L3751V12 Evaluation board

     The STMicroelectronics STEVAL-L3751V12 evaluation board has a wide input voltage range of 6V to 75V, with an extremely high voltage conversion ratio across the switching frequency range. The board provides a 5V stabilized voltage output at a switching frequency of 230kHz. The output voltage on the STEVAL-L3751V12 board is quickly set to 12V via a jumper connector. Select different voltage outputs by changing the resistor to a lower VIN range.

     The STM STEVAL-L3751V12 board is a 100W demo board. The maximum default current is set to 15A, easily selected by changing the resistor. The board is based on the L3751 synchronous step-down controller, in VQFN package realizes voltage mode, has internal compensation function, can minimize design complexity, reduce size.

     Embedded protection features such as output overcurrent, input voltage UVLO, internal voltage monitoring, and heat off at 150°C enable controlled, safe operation in critical environments in telecommunications, networking, and industrial applications.
